Owen brings Amelia to see the new house he bought because she was tired of his trailer. Their earlier conversations about marriage, though only half-serious, are clearly on her mind. "Why aren't we doing it? Why aren't we building our life?" she asks. "I don't want to waste our time... I want a real life, and I want it with you." Owen is surprised. "Are you asking me to marry you?" he asks. "Yes!" she says. Watch this scene from Season 12, Episode 23, "At Last" and don't miss Grey's Anatomy THURSDAYS 8|7c on ABC.
